Physics
Consider a swimmer who wants to swim directly across a river. If the speed of the current is 0.31 m/s and the swimmer's speed relative to the water is 0.57 m/s, how long will it take her to cross a river that is 13 m wide?

A baseball is hit with an initial speed of 42 m/s at an angle of 30° relative to the x (horizontal) axis.(a) Find the speed of the ball at t = 3.4 s. (b) What angle does make with the x axis at this moment? (c) While the ball is in the air, at what value of t is the speed ...

Physics
A bullet is fired from a rifle with a speed v0 at an angle è with respect to the horizontal axis from a cliff that is a height h above the ground below. Calculate the speed of the bullet when it strikes the ground.

Physics
A block slides down an inclined plane that makes an angle of 23° with the horizontal. There is friction between the block and the plane. If the acceleration of the block is 2.1 m/s2, find the coefficient of kinetic friction between the block and the plane.
